(Cl. 240-415) This invention relates generally to lamps for Themounting D for the units preferably commotor vehicles, especially headlamps, and conprises dished seats 25 and 28, respectively, whichstitutes a division of our application filed March are separate andindependent ring-like members 15, 1937, bearing Serial No. 131,084, nowPatent or collars that are individually mounted upon a No. 2,138,079issued November 29, 1938. frame 2? welded to the lamp casing A. Prefer-5 One of the essential objects of the invention ably the seat 25 for theunit B has a lateral is to provide a head lamp wherein provision isflange 28 substantially parallel to a vertical flange made forindividually mounting a plurality of 29 of the frame 2i and isadjustably connected lighting units upon a common support wherebythereto by three screws 3B, 31 and 32, respecone of said units isadjustable relative to the tively, while the seat 26 for the unit C hasa 10 other. lateral flange 33 overlapping and fastened to an Anotherobject is to provide a head lamp offset portion 34 of the frame 27 bythree screws wherein the mounting means is simple in con- 35, 36 and 3?,respectively. Thus, by adjusting struction, economical to manufacture,and easy the screws 36, Si and 32 for the seat 25, the
